Speed Controller

Product Details:

The RSHR Midi is a compact easy-to-use AC semiconductor motor controller. With this controller 3-phase motors with nominal currents up to 18A can be soft started and/or soft stopped. The RSHR Midi controls 2 phases only, one phase is continously connected to the load. Soft starting and soft stopping is achieved by controlling the motor voltage. During running operation the semiconductors are bypassed by internal electromechanical relays. Starting and stopping time as well as initial torque can be independently adjusted by built-in potentiometers. LEDs indicate the status of the controller including an alarm status in case of overtemperature in the RSHR...V21 models. The RSHR Midi comes with an integrated heatsink and is ready to mount on DIN rail.

Product Details:

Compact easy-to-use AC semiconductor motor controller. With this controller single phase capacitor run induction motors with nominal load currents up to 12 A can be soft-started. Starting time as well as initial torque can be independently adjusted by built-in potentiometers. Torque reduction by ramping of a single phase in 3-phase applications is also possible with this module.

Product Details:

The speed control unit is rugged enough to be placed in a control cabinet or engine mounted enclosure with other dedicated control equipment. If water, mist, or condensation may come in contact with the controller, it should be mounted vertically. This will allow the fluid to drain away from the speed control unit. Extreme heat should be avoided. An overspeed shutdown device, independent of the governor system, should be provided to prevent loss of engine control, which may cause personal injury or equipment damage. Do not rely exclusively on the governor system electric actuator to prevent overspeed. A secondary shutoff device, such as a fuel solenoid, must be used.
